Queenslanders Rod and Mary Burrows, who went missing on flight MH370, will be farewelled this Sunday.

The private service in Brisbane this weekend is understood to be the first memorial of any of the missing Australians.

The Burrows had three children and one grandchild, who was born since they went missing.

Their son Jayden said in April they would dearly miss their mother and father, who he said had worked hard to set themselves up to enjoy their retirement.

"We're heartbroken that this stage of their life has been cut short," Mr Burrows said.

The Burrows had been on the flight with their friends Catherine and Robert Lawton, also from Brisbane. Li Yuan and Gu Naijun, from Sydney, are the other two missing Australians.

Malaysia Airlines has announced it will stop providing hotel accommodation for the families of those missing on May 7, encouraging relatives to receive any further information from "the comfort of their own homes".

The airline released a preliminary report on the flight's disappearance, as well as the cockpit audio, which contained those last words heard from the plane, "good night Malaysian-370".
